Installation in a triangular groove
Mounting spaces with a triangular form are sometimes
used with threaded flanges and covers.
It is, however, difficult to manufacture them with exact
dimensions.
As the sealing function of the ISC O-Ring depends on
the exact design of the mounting groove, it is impera-
tive that the dimensions and tolerances stated in the
following table be adhered to. Fitting into a rectangular
groove is preferred, however.
